Reported by Ohbong Kwon (NMSC Chair, VP1)
The National Math and Science Contest (NMSC) is one of the flagship events hosted by KSEA. The NMSC 2025 was held on Saturday, April 5, 2025, marking the fully in-person contest the same as in 2024. Nearly 1,000 students from 4th through 12th grade in 22 different locations across the nation. With the great help and dedication of the Chapter Presidents (CPs) and NMSC Chairs and volunteers of each chapter, the NMSC 2025 was largely successful.
The award ceremony was held online two weeks later, on April 19, 2025, to recognize the top performers in each grade.
The NMC 2025 National Awards recipients are listed below with their school and residence areas. The national award winners have been invited to the Hanwha Math Olympias (HMO) on May 17, 2025.
